Answer:
c. x = -1/15
Step-by-step explanation:
5/2x - 1/3 = -1/2 [multiply the whole equation by 6 (lowest common denom)
15x - 2 = -3 [add 2 on both sides of equation
15x = -1 [divide both sides by 15 to isolate x]
x = -1/15
If 12 juice boxes cost $4.20 how much would fifteen juice boxes boxes cost
Answer:
$5.25
Step-by-step explanation:
Calculation for how much would fifteen juice boxes cost
Cost of fifteen juice boxes=15/12=x/$4.20
Cost of fifteen juice boxes=x=15*$4.20/12
Hence,
x=63/12
x=$5.25
Therefore the amount that the fifteen juice boxes would cost is $5.25
Answer:
$5.25
Step-by-step explanation:
First, we need to divide $4.20 by 12.
4.20 / 12 = 0.35
We now know that a juice box costs $0.35.
Now, multiply $0.35 by 15.
0.35 * 15 = 5.25
So the answer is $5.25.
I hope this helps!

Javier is helping his parents put up posters in their movie theater. Each poster has a thickness of 0.012 inch. How thick is a stack of 10 posters? 100 posters? 1,000 posters?
and why
Step-by-step explanation:
1=0.012inch
10=0.012x10
10=0.12inch
100=0.012x100
100=1.2inch
1000=0.012x1000
1000=12inch
because if 1 poster has a thickness of 0.012 inch
than you have to multiple the number of posters with 0.012 inch

Find the value of A in the following expression
x³ + x² - 2Ax + A² has remainder 8 when divided by x - 2
Answer:
Let p(x) = x3 + ax2 + bx +6
(x-2) is a factor of the polynomial x3 + ax2 + b x +6
p(2) = 0
p(2) = 23 + a.22 + b.2 +6 =8+4a+2b+6 =14+ 4a+ 2b = 0
7 +2 a +b = 0
b = - 7 -2a -(i)
x3 + ax2 + bx +6 when divided by (x-3) leaves remainder 3.
p(3) = 3
p(3) = 33 + a.32 + b.3 +6= 27+9a +3b +6 =33+9a+3b = 3
11+3a +b =1 => 3a+b =-10 => b= -10-3a -(ii)
Equating the value of b from (ii) and (i) , we have
(- 7 -2a) = (-10 - 3a)
a = -3
Substituting a = -3 in (i), we get
b = - 7 -2(-3) = -7 + 6 = -1
Thus the values of a and b are -3 and -1 respectively.

The value of x is 5 from the diagram.
The sum of angles in a triangle.The sum of interior angle of a triangle is 180 degrees. Hence:
m<A + m<B + m<C = 180From the information given,;
73 = 8y - 7 (base angles are equal)
8y = 80
y = 10
Take the sum of the angles:
73 + 6x + 4 + 73 = 180
6x + 150 = 180
6x = 30
x= 5
Hence the value of x is 5 from the diagram.

The value of x is 5.
Since triangle ABC is an isoceles triangle, angle A = Angle C(base angles of an isoceles triangle are equal)
Since angle A = 73° and angle C = (8y - 7)°
angle A = angle C
⇒ 73 = 8y - 7
Adding 7 to both sides, we have
73 + 7 = 8y - 7 + 7
80 = 8y
Dividing both sides by 8, we have
y = 80/8
y = 10
Also, angle A + angle B + angle C = 180° (sum of angles in a triangle)
73 + 6x + 4 + 8y - 7 = 180
Collecting like terms, we have
73 + 4 - 7 + 6x + 8y = 180
6x + 8y + 70 = 180
Subtracting 70 from both sides, we have
6x + 8y + 70 - 70 = 180 - 70
6x + 8y = 110
Making x subject of the formula, we have
6x = 110 - 8y
x = (110 - 8y)/6
Substituting the value of y into the equation, we have
x = (110 - 8y)/6
x = (110 - 8 × 10)/6
x = (110 - 80)/6
x = 30/6
x = 5
So, the value of x is 5.

solve this by elimination method plzzzzzzzzzzzzz helppppppppppppp meeeeeeeeeee
Answer:
[tex](\frac{10}{3}, 1)[/tex]
Step-by-step explanation:
1) In order to solve a system of equations with the elimination method, you need to add or subtract the two equations and "eliminate" variables by canceling out terms. This leaves you with an equation with only one variable to solve. Then, once you solve that equation, you can substitute the answer you got into one of the system's equations to find either the x or y value.
This problem already has one 3x in each equation, so let's focus on canceling that term out, eliminating the x variable. To set up this situation, we need one 3x to be negative, so let's multiply the terms in 3x-6y = 4 by -1, which gets us to -3x + 6y = -4. Now let's "cancel out" those x variables by adding them together. (This work is shown in the first picture.)
Remember to add the other terms. This leaves us with the equation 13y = 13. By isolating y, we can find its value, which leaves us with y = 1.
2) Next, let's substitute 1 for y in one of the two equations. In this case, I used 3x + 7y = 17. Then, isolate x to find its value:
[tex]3x + 7 (1) = 17\\3x + 7 = 17 \\3x = 10 \\x = \frac{10}{3}[/tex]
Therefore, the answer would be [tex](\frac{10}{3} , 1)[/tex].

When sandy and allen's mother decorates the house by herself, it takes her 5 hours.When both Sandy and Allen help, the three can finish the job in 2.5 hours.
If you're asking how this is possible,
Answer and explanation:
If Sandy and Allen's mother does the job in 5 hours
And Allen and Sandy's contributions completes the job in 2.5 hours
5 hours - 2.5 hours =2.5 hours
Allen and Sandy's contribution is half of the time it took only Allen and Sandy's mother= 2.5 hours
Therefore Allen and Sandy together will take 2.5×2 = 5 hours to complete the job alone without their mother
A similar example: if it takes one person 2 hours to peel 5 potatoes and it takes 1 hour to peel same number of potatoes if a second person helps, then this second person reduces the time used by 1 hour(50%) and would take 2 hours to complete the work.

Answer:
78
Step-by-step explanation:
11 + x = 89 Subtract 11
11 - 11 + x = 89 -11
x = 78
Step-by-step explanation:
Hey there!
Given;
y+x= 89.......(a)
y = 11
~ Substitute the value of y on equation (a)
11+x = 89
~ Subtract 11 from both sides.
11+X -11 = 89-11
x = 78.
Therefore, the value of x is 78.
